CArputer install and need info

I have a Sony VAIO desktop with a 1.6 GHZ Celeron. I am going to do a carputer install within the next couple of months and am researching what power supply to use. Some mother boards are called ITX and some are called ATX and I don't know what to do as far as power supply is concerned. Please help...

Look at the label on the back of the computer you intend to use. It will tell what the maximum wattage rating is. If it is 150 watts or less, you can go with a DC-DC solution. Otherwise, you can get an inverter that matches the rating. For good measure, get one with a healthy margin above that (i.e. get a 300 watt inverter for a 200 watt computer).
